On 26 November the Commander-in-Chief Middle East Command, GeneralSir Claude Auchinleck, replaced Cunningham with Major-GeneralNeil Ritchie,[2] following disagreements between Auchinleck and Cunningham. Despite achieving a number of tactical successes, Rommel was forced to concede Tobruk and was pushed back to El Agheila by the end of 1941. In February 1942 Rommel had regrouped his forces sufficiently to push the over-extended Eighth Army back to the Gazala line, just west of Tobruk. Both sides commenced a period of building their strength to launch new offensives but it was Rommel who took the initiative first, forcing the Eighth Army from the Gazala position.[3]

Ritchie proved unable to halt Rommel and was replaced when Auchinleck himself took direct command of the army. The Panzer Army Afrika were eventually stopped by Auchinleck at the First Battle of El Alamein. Auchinleck, wishing to pause and regroup the Eighth Army, which had expended a lot of its strength in halting Rommel, came under intense political pressure from British Prime MinisterWinston Churchill to strike back immediately. However, he proved unable to build on his success at Alamein and was replaced as Commander-in-Chief Middle-East in August 1942 by General Harold Alexander and as Eighth Army commander by Lieutenant-GeneralWilliam Gott. Gott was killed in an air crash on his way to take up his command and so Lieutenant-General Bernard Montgomery was appointed in his place. Alexander and Montgomery were able to resist the pressure from Churchill, building the Army's strength and adding a pursuit formation, X Corps, to the Army's XIII and XXX Corps.[4]

Following three unsuccessful attempts in early 1944 by the U.S. Fifth Army to break through the German defensive positions known to the Allies as the Winter Line, the Eighth Army was covertly switched from the Adriatic coast in April 1944 to concentrate all forces, except the V Corps, on the western side of the Apennine Mountains alongside the U.S. Fifth Army in order to mount a major offensive with them. This fourth Battle of Monte Cassino was successful with the Eighth Army breaking into central Italy and the Fifth Army entering Rome in early June.[8]

After the Allied capture of Rome the Eighth Army continued the fight northwards through central Italy to capture Florence. The end of the summer campaign found Allied forces butting up against the Gothic Line. The Eighth Army returned to the Adriatic coast and succeeded in forcing the Gothic line defences, but ultimately the Allied forces could not break into the Po valley before the onset of winter forced an end to serious offensive operations. During October, Leese was reassigned to South East Asia Command, and Lieutenant-General Sir Richard L. McCreery, who had previously commanded X Corps, replaced him.[9]

The final offensive in Italy saw the Eighth Army back in action. Working in conjunction with the U.S. Fifth Army, now commanded by Lucian K. Truscott, on its left flank, it cut off and destroyed, (during April), large parts of the opposing Army Group C defending Bologna and then made a rapid advance through northeast Italy and into Austria. Problems occurred where British and Yugoslavian forces met. Josip Broz Tito's forces were intent on securing control of the area of Venezia Giulia. They arrived before British forces, and were very active in trying to prevent the establishment of military government in the manner that had applied to most of the rest of Italy. They even went as far as to restrict supplies through to the British zone of occupation in Austria and tried to take over part of that country as well. On 2 May 1945, the 2nd New Zealand Division of the Eighth Army liberated Trieste, and that same day, the Yugoslav Fourth Army, together with Slovene 9th Corpus NOV entered the town. During the fighting on the Italian Front the Eighth Army had, from 3 September 1943 until 2 May 1945, suffered 123,254 casualties.[10]

In its early days, the Eighth Army had seen many tribulations. However, after the Second Battle of El Alamein, the worst that could be said of its operations was that they degenerated into temporary stalemates. Its advance from El Alamein to Tunisia was one of the greatest military logistical feats of all time, and it had distinguished itself fighting under difficult conditions during the campaign in Italy. It ended its days by being redesignated British Forces in Austria; controlling the British forces occupying part of that country. In this capacity Trevor Howard appears in the 1949 film, The Third Man, as "Major Calloway", an Eighth Army Royal Armoured Corps officer.[11]

After the war, veterans from the Eighth Army organized Annual Reunions at the Royal Albert Hall. Then, in the late 1970s, the Eighth Army Veterans Association was formed. At the height of its membership, there were over 35 branches, with a particular strength in the North West of the UK.[21]
